Patented Jan. 1, 190?.

To a, whom it may concern:

Be it known that 1, Louis Mr'nns, a citizen of the United States, residing at Newark, in the countyiof Essex and State of New Jersey,

have invented certain new and uselul. im-

provements in Draft-Producing :2 its; and i. do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it lappertains to make and use the v same, reference being hen. to ti 3 accompanyting drawings, and to figures reference marked thereon, wliiiciii form a ut of this specification.

.The objects of this invention are to economize power in the operation of fans employed more especially in securing circulation of air in a room or apartment; to provide a more inexpensive and durable structure and one which may be readily kept repair; to

secure a device that can be convei'iiently transported from place to place, and ti us to enable a movement of air to bedirected to points where a draft is especially needed; to avoid the use of connections with distantsources of power, and to secure other advantages and results, some ofwhich may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved portable fan and in. the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claiin.

Referring to the accompanying drawings,

in which like numerals of reference indicate corresponding parts in each of the several figures, Figure l is a front elevation of my improved device. the same. Fig. 3 is a view showing certain parts of the interior construction, the front plate, fan, spring, and immediate connections being remhved.- Fig. 4 is a sectional view taken atjline' 00. Fig. 5 is a similar sectional view looking in the reverse direction. Fig. 6

is a side elevation of the device, and'Figs. 7

Fig. 2 is a rear elevation of preferably east inte al with the post 10 and provides .iuteriorly, at the front thereof, bosses 121, having female threads 122, to which the front plate H of the is secured by n'ieans of screws 123 or otherwise. The said front plate supports the center plate 13 by means of studs or posts 17 and cooperating screws, (not shown in full lines) and the rear plate 19 separa bly secured to said center plate 13 by similar l10ll0W posts or studs 18 and screws 191.. The plates let, and 19, with their posts or studs and screws, form. a i? 1c of rrioovaii. parts. "i no wheel 4'1 and front Winning means being first detached and the front plate 14 being detached from the casing 12, the rear plate 19, center plate 13, and spring-carrying plate can be removed from behind through the rear opening of the casing. Between the front plate 14 and the center plate 13 of the said reincvable frame is a spring-carrying plate 25, arrai igi-id loosely on a hub or shaft 25, extending forw d from a hearing at the center of the eel t pla Said hub stepped, shown in i, smaller end lying in the center plate, the next larger step providing a pivot for the spring-rarrying plate, and the enlarged part of the hub being within the spring 28 and having a pin or arm 29, to which the inner end of the spring secured. The said hub 26 is provided at the axial center with a female thread to receive a pivotal extension. 30 of a winding device 31, having radial handles 32, the said winding device being prelerabl 1 a frame-like structure adapted to lie around and a little away from the periphery of the fan-Wheel 47 to protect the same in service, the said frame serving to guard the wings of the fan-wheel from injury or from injuring the hands of a person handling the device in transuirtatioii or otherwise. "llhe winding device 31 when turned in one dirlection serves to turn the hub 26 and wind up the spring 28. When turned in the reverse directioinit un- Winds the spring, and if turning is continued it is simply unscrewed from the hub, so as to be removed when disassociating the parts.

The front plate 14, preferably at the front side thereof, is provided with a pawl 34;,

upon the pivotal arbor 30 of the winding do direction towvind the spring ,7 1 hut by vice or to said winding device. Thus under adapted to engage a THIChQtvV/hfifll 35, fixed 7 in late and transmits )ower in connecb 7 train of gear-wheels the movement of the fantain oil the portable casing of a removable front plate,

I tween said front plate and center plate, a hub raising the pawl from the ratchet-wheel the said winding devicecan be" unscrewed and unwound, as above referred to.

On the hub 26 on one of its rearward steps is preferably arranged in connection with the spring-carrying plate 25 a gear-w heel 36, which turns on the hub with said spring-car tion with a train of gear-wheels, to a pinion 37 on the fan-wheel shaft 38.. The power of the spring 28 is thus transmitted, through i said carrying-plate .25, gear-Wheel 36, and the series or train of cooperating gear-wheels 37', 39, 40, 41, 42, 43, 4A, 45, and 46, to a central fan-carrying shaft 38, upon which the fanwheel 47 is stationed, the hub 26 and its-pivotal or stepped extension and the pivotal and threaded shaft 48 of the winding device 31. being each hollow to permit a passage to said fan-carrying shaft. By this construction the power of the spring 28 is transmitted to the fan-wheel 47, and because of the series or Wheel is greatly quiekened, so that it rotates at a very high rate of speed to effect the desired propulsion or circulation of air.

It may be noted here that by simplyunscrewing the front plate 14 from the annular casing 12, integral with the stand, and removing the fan-wheel and winding device'at the front of said front plate the interior working parts can .be' Withdrawn from said casing and be thus exposed, so that .the same can be easily lubricated, cleaned, or otherwise manipulated, thus conducing to convenience in repair, cleaning, or lubricating.

I am aware that various and numerous detail chan es may be made in the construction of my evice without departing from the spirit or scope of my invention,'and,while I have in positive terms detailed the preferred construction-I do not wish to be understood as limiting myself by such positive descriptive, terms; but, on the'coiitrary, Iiwish my claims to be understood in their broadest interpretation, only restricted by the state of the art. I
